From the drawing it may be seen the movable frame of this invention is adapted to be centered by movement in either direction parallel to the general plane of the frame members when closed and also by movement of the movable frame member substantially normal to the plane of the stationary frame member. An inclined or'cam surface forming less than 45 with any of these directions of movement aids in this centering movement. Another feature is the cutting away of a portion of the rigid cam surfacesat the vertex of a pair of adjacent cam surfaces which form an angle of less than not only to provide space for an internal Weatherstrip, which need not be necessarily used, but also in case the cooperative cam surfaces do not precisely abut, more of an opportunity for an interfltting movement is provided by removal of a part of a limiting abutment at the vertex.

The term "exposed side occurring in the claims is not intended to imply that the frame members may be only of polygonal shape.

I claim:

1. stationary and movable frame members for a. wall opening, each having on its face adjacent the other frame member and on its exposed sides at least three guide surfaces adapted to abut cooperative surfaces on the other frame member when the movable frame member is closed, two of said guide surfaces on each frame member being at a larger acute angle to the plane.

of the frame member than is the guide surface intermediate said two.

2. A closure for a wall opening having fixed and movable frame members at least one of which has on its face adjacent the other frame member and on its exposed sides. an internal weatherstrip on each side of which is a cam surface, the other of said members having a rib with an edge formed by two cam surfaces each forming an acute angle to the planes of said frame members when closed, at least one of the rib cam surfaces being adapted to engage one of the cam surfaces of the member having the weather-strip to assist in positioning the movable member in closing, the cam surfaces of one member substantially abutting the cam surfaces of the other member whenthe movable member is closed and the edge of said rib engaging and deforming said strip.

3. A closure for a wall opening having fixed and movable frame members, each of said frame members havin on one face thereof and'on each exposed side, at least two cam surfaces which substantially abut the complementary cam surfaces of the other frame member, one pair of abutting cam surfaces forming an angle of less than 45 with the general plane of the frame members when in closed position and the other pair of abutting cam surfaces forming an angle of substantially more than 45 with the general plane of the frame members.

4. A closure for a wall opening having fixed and movable frame members, each frame member having on one face and on each exposed side, a plurality of cam surfaces which are adapted to engage cooperative cam surfaces on the other frame member and being so arranged that relative movement between said frame members either in the direction of their plane or substantially normal thereto tends to center the movable frame member into closed position by engagement with a cam surface forming an angle of not more than 45 with the direction of said movements.

5. A closure for a wall opening having fixed and movable members each of which has on at least one face thereof and on each exposed side a pair of adjacent cam surfaces adapted to cooperate with cam surfaces on the other member to assist in centering the closure, said cam surfaces forming an angle of less than 180 to one another on one member and more than 180 on the other and each surface forming an acute angle to the plane of the members when closed. the vertex of said adjacent cam surfaces forming an angle less than 180 being cut away in at least one of the members to remove a portion of a rigid limit in width of each cam surface in event the cooperative cam surfaces may not abut throughout their full area.

6. A closure for a wall opening comprising fixed and movable members one of which has on at least one face thereof on each exposed side a pair of adjacent cam surfaces adapted to abut cooperative cam surfaces on the other member to assist in centering the closure, said pair of cam surfaces on one member forming an angle of less than 180 and on the other member the cooperative surfaces forming an angle greater than 180, one cooperative or abutting pair of cam surfaces forming an angle of not more than 45 to the general plane of said members and the other pair of abutting'cam surfaces forming an angle of not less than 45 to the plane of said members, the vertex of the adjacent cam surfaces forming less than 180 being cut away to remove a portion of a rigid limit in width of each cam surface in event the cooperative surfaces may not fully abut.
